Generator Fuel Options: What’s the Difference?

As homeowners compare whole-home generator models, fuel type is a key consideration. Each of the three most popular generator fuel options has distinguishing advantages and setbacks.



Selecting the optimal fuel type is vital for generator performance, maintenance, and reliable home power during outages. Let’s explore the differences between diesel, natural gas, and propane generators to help you decide which fuel option best aligns with your needs.

Diesel

Diesel fuel is popular for whole-home generators because it is efficient, cost-effective, and readily available. It is often the go-to choice for many homeowners because it provides reliable power during prolonged outages. However, diesel generators can be louder, which might be a consideration if noise is an issue in your neighborhood. Keep in mind that diesel may be difficult to acquire in a crisis when emergency generator services are needed.

Key Traits

• The most efficient fuel option
• Diesel generators require less maintenance
• Require additives to maintain shelf life

Natural Gas

Natural gas generators are connected directly to your home's gas line to provide continuous power without refueling. Natural gas burns cleaner than diesel, making it a more environmentally friendly choice. However, the downside is that natural gas offers the lowest power output of the three main fuel options. Natural gas lines can also be disrupted in severe weather, potentially affecting your generator's reliability.

Key Traits

• The most abundant generator fuel option
• Does not require refueling
• Burns cleaner and is more environmentally friendly

Propane

Unlike other fuels, propane does not degrade over time, making it ideal for infrequent use. Propane tanks can be stored safely and are often available in portable sizes, offering flexibility in placement and usage. However, the initial cost of propane generators can be higher, and you need space to store propane tanks. Despite these initial costs, propane generators' long-term benefits and clean operation make them a solid choice for many families.

Key Traits

• Versatile and long shelf life
• Safe, portable storage options
• Cleaner burning, reducing emissions

Choosing the right generator fuel option depends on your specific needs and circumstances. Consider each fuel type's pros and cons and consider factors like availability, cost, and environmental impact.
